C data types to Visual basic C data types to Visual basic Jeffrey (Programmer) (OP) 1 Nov 99 14:19 I am trying to read two variables in to a Visual Basic program that where created in C. The data types are int64 and datetime. Any Suggestions? RE: C data types to Visual basic chiph (Programmer) 1 Nov 99 16:28 Hi Jeffrey! As you've found out, VB doesn't have any 64-bit datatypes and can't read these directly. However, you might try reading them as two LONGs. Chip H.
